I am programming in c++ MFC,
我在c++ MFC编程，
I want to get "C:\windows" "c:\program files" folder path.
我想要“C:\windows”“C:\程序文件”文件夹路径。
Sometimes user may setup windows in other folder such as c:\windows0.
有时用户可以在其他文件夹中设置窗口，比如c:\windows0。
Is there any API to get absolute path of the windows and program files path?
是否有任何API可以获得windows和程序文件路径的绝对路径?
Many thanks!

For the Windows folder:
Windows文件夹:
TCHAR windir[MAX_PATH];
GetWindowsDirectory(windir, MAX_PATH);
For program files:
程序文件:
TCHAR pf[MAX_PATH];
SHGetSpecialFolderPath(
0,
pf,
CSIDL_PROGRAM_FILES,
FALSE );
Where MAX_PATH comes from the Windows headers and will guarantee the buffer is long enough for the longest (non-UNC) path.
其中MAX_PATH来自于Windows header，并保证缓冲区足够长，可以用于最长的(非unc)路径。
Also, note that SHGetSpecialFolderPath can be used to retrieve other "special" folder including the Windows folder just by replacing the third parameter to any from this list.
另外，请注意，可以使用SHGetSpecialFolderPath检索其他“特殊”文件夹，包括Windows文件夹，只需将第三个参数替换为该列表中的任何一个。

Most of these come from SHGetFolderPath, but GetSystemDirectory() returns the absolute location of C:\Windows\System32. Don't use GetWindowsDirectory(). It doesn't do what you want anymore.
其中大部分来自于SHGetFolderPath，但是GetSystemDirectory()返回的绝对位置是c:windowssystem32。不要使用GetWindowsDirectory()。它不再做你想做的事了。

On Vista+, SHGetKnownFolderPath is the replacement for SHGetFolderPath and SHGetSpecialFolderPath, although you can continue to use the older functions if you need backward compatibility to older versions of Windows.
在Vista+中，SHGetKnownFolderPath是SHGetFolderPath和SHGetSpecialFolderPath的替代品，但如果您需要向后兼容旧版本的Windows，则可以继续使用旧函数。
